Hello Ben,

 

this looks strange and is probably not intended. The behaviour should be similar for IP address and network interface name.

 

Could you please create an issue on our tracker about it?

 

Cheers,

 

Henning

Not using IPv6.  I've created a contianer to easily identify this. After starting the rpc command core.psx is called and it's output printed.

 

By default eth0 will be used:

 

docker run --rm -it whosgonna/kamsockets

 

 

To use a specific address (and 0.0.0.0 is the easiest), pass it as an environmental variable:

 

docker run --rm -it -e INTERFACE=0.0.0.0 whosgonna/kamsockets

 

 

The script, etc. can be found here:

Hi Kaufmann,

 

 

did you run ipv6 and the extra listener are ipv6? 

 

Kind regards

At a quick glance it looks like using socket_workers when the listen parameter uses the interface name does not work.  For example:

 

children = 4

socket_workers=2

listen=udp:10.10.10.10:5060

 

Gives two listeners on udp:10.10.10.10:5060

 

 

children = 4

socket_workers=2

listen=udp:eth0:5060

 

Gives four listeners on the socket.

 

Note this is just a quick cursory observation.  Is it by design or a design limitation?
